DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings: The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings within the present invention based on the specific circumstances.

[0017] like Figure 1 、 Figure 2 and Figure 3 As shown, a multifunctional recycling and processing device for construction waste includes a crusher 1, a conveyor belt 2 is fixedly installed at the bottom of the crusher 1, and a magnetic separator 3 is fixedly installed on the conveyor belt 2. The device first crushes the construction waste through the crusher 1, and then separates the metal such as steel bars in it through the magnetic separator 3 during transportation. Then, with the cooperation of the air separation mechanism 9 and the air separation cylinder 4, the light waste such as plastic in the construction waste is separated, and the sorted materials are screened. The materials with fine particles and soft texture are discharged from the fine material outlet 502A and used for the production of recycled powder materials or lightweight wall panels. The remaining large particles and good quality materials are repeatedly washed with water and used again for recycled concrete.

[0018] A wind separation drum 4 is fixedly provided at the rear end of the conveyor belt 2, and a wind separation mechanism 9 is rotatably connected inside the wind separation drum 4. By setting the wind separation drum 4 and the wind separation mechanism 9, when the crushed building materials are sent in, the light-weight small-particle building materials and light garbage are affected by the airflow, cross the runner 902, and fall from the rear. After being vibrated and screened by the screen plate 903, the small-particle building materials continue to fall through the opening 407 into the screening chamber 502, while the heavier building materials are less affected by the airflow, fall directly, and enter the screening chamber 502 from the opening 407.

[0019] like Figure 4 and Figure 5 As shown, the left side of the air separation mechanism 9 is fixedly connected to a screening mechanism 10, and the left side of the screening mechanism 10 is fixedly connected to a stirring mechanism 11. By arranging a spray drum 13, a drum 6 and a stirring mechanism 11, the screened construction materials are subjected to multiple water washing operations. The materials are first repeatedly pushed and rubbed by the stirring mechanism 11 in the stirring chamber 501 to peel off the dirt and other difficult-to-clean outer layer of the materials. When the materials enter the drum 6, they are continuously moved to the right and soaked under the push of the forward-rotating water washing push paddle 601, move to the right into the feeding hole 1202, and enter the spray drum 13 under its rotation for spray cleaning, and continue to move to the left under the push of the reverse-rotating water washing push paddle 1301 and finally fall back into the drum 6. Therefore, they can be repeatedly soaked and sprayed to ensure the water washing effect of the construction materials. The stirring mechanism 11 includes a counter-rotating stirring paddle 1101 and a forward-rotating stirring paddle 1102. Both the counter-rotating stirring paddle 1101 and the forward-rotating stirring paddle 1102 are located in the stirring chamber 501. When the counter-rotating stirring paddle 1101 rotates forward along with the rotating drum 6, and the forward-rotating stirring paddle 1102 rotates forward along with the screening circle 1001, the building materials are repeatedly pushed by the two, repeatedly rolling and moving horizontally inside the stirring chamber 501, promoting friction between the materials and improving the subsequent water washing efficiency.

[0020] The left side of the air separation cylinder 4 is fixedly connected with a fixed shell 5. Figure 6 As shown, a screening chamber 502 is provided inside the fixed shell 5, and the screening mechanism 10 is rotatably connected to the inner wall of the screening chamber 502. A fine material outlet 502A is fixedly opened at the bottom of the screening chamber 502, and the material with smaller particles screened out is discharged from the fine material outlet 502A; a stirring chamber 501 is provided on the left side of the screening chamber 502, and the stirring mechanism 11 is rotatably set in the stirring chamber 501, and a drain outlet 501A is fixedly opened at the bottom of the stirring chamber 501. The water sprayed from the spray pipe 14 first sprays and cleans the material in the spray drum 13. The flushed water flows into the drum 6 for the first soaking of the material, and then enters the stirring chamber 501 through the water hole 1203, and soaks the material in the stirring friction for the second time, assisting the soil to separate from the material, and finally the cleaning wastewater mixed with soil is discharged from the drain outlet 501A.

[0021] The left side of the fixed shell 5 is rotatably connected to the drum 6. A feed cone 12 is fixedly provided at the right end of the inside of the drum 6. By setting the feed cone 12, when it rotates forward with the drum 6, the reverse-rotating propeller 1201 pushes the material in the stirring chamber 501 to the right, preventing the building materials from entering the inside of the drum 6. The reverse-rotating water-washing pusher 1301 pushes the material from the right side of the spray drum 13 into the drum 6, while the forward-rotating water-washing pusher 601 pushes the material in the drum 6 to the discharge valve pipe 7 on the left side of the drum. The cleaned materials are discharged. As the feed cone 12 rotates in the opposite direction to the drum 6, the counter-rotating propellers 1201 push the pre-treated building materials in the stirring chamber 501 into the drum 6 and the spray drum 13, where they are repeatedly soaked and sprayed to clean the materials. A spray drum 13 is located on the left side of the feed cone 12. This is fixedly connected to the inner wall of the drum 6 via a connecting arm. A discharge valve pipe 7 is fixedly connected to the left end of the drum 6. A power mechanism 8 is located on the left side of the discharge valve pipe 7. Driven by this power mechanism 8, the discharge valve pipe 7, the drum 6, the spray drum 13, the feed cone 12, and the counter-rotating stirring paddles 1101 rotate synchronously to perform various material treatments.

[0022] like Figure 7 and Figure 9 As shown, a feed pipe opening 401 is fixedly provided on the upper side wall of the front portion of the air separation cylinder 4, and an air outlet frame 402 is fixedly provided at the lower portion of the feed pipe opening 401. A partition 408 is fixedly connected to the inner wall of the bottom of the air separation cylinder 4. The partition 408 is provided to prevent airflow chaos and ensure a single path for the airflow, allowing the airflow to blow upward from the air outlet frame 402 and return from the air collection frame 403. An air collection frame 403 is fixedly provided on the top of the air separation cylinder 4, and a plurality of groups of air guide plates 403A are fixedly connected to the inner wall of the air collection frame 403. The provision of the air guide plates 403A allows the direction of the airflow to change suddenly before being discharged from the air collection frame 403. Light materials and small particles of construction materials can escape from the airflow under the action of inertia and fall onto the sieve plate 903, preventing the airflow from carrying light garbage and the like and accidentally flowing into the air collection frame 403. A ventilation pipe 404 is fixedly connected to the front outer wall of the air collection frame 403, and a fan 405 is fixedly installed on the ventilation pipe 404. The other end of the fan 405 is fixedly connected to the air outlet frame 402 through the ventilation pipe 404. A light material outlet 406 is fixedly opened on the rear side wall of the air separation cylinder 4, and a slot 406A is fixedly opened on the inner wall of the light material outlet 406. An opening 407 is fixedly opened at the bottom of the left side wall of the air separation cylinder 4. By setting the opening 407, building materials can enter the screening chamber 502 from the air separation cylinder 4 for screening operations.

[0023] like Figure 10 and Figure 11As shown, the air separation mechanism 9 includes a second drive motor 901, which is fixedly mounted on the right outer wall of the air separation drum 4. The rotating shaft of the second drive motor 901 is fixedly connected to a runner 902, on which a plurality of top blocks 902A are fixedly mounted. The runner 902 is rotatably mounted inside the air separation drum 4. A sieve plate 903 is provided at the rear of the runner 902. The bottom sides of the sieve plate 903 are rotatably connected to the slots 406A. The bottom sides of the sieve plate 903 are also fixedly connected to torsion springs 904, the other ends of which are fixedly connected to the slots 406A. The top of the sieve plate 903 is fixedly connected to a protrusion 903A. Driven by the torsion springs 904, the top of the sieve plate 903 maintains contact with the runner 902. As the runner 902 rotates, the top blocks 902A repeatedly lift and lower the protrusions 903A, causing the sieve plate 903 to vibrate slightly, thereby accelerating the screening of small-particle building materials.

[0024] like Figure 8 and Figure 12 As shown, the screening mechanism 10 includes a screening circle 1001, which is rotatably connected to the inner wall of the screening chamber 502. The right side wall of the screening circle 1001 is fixedly connected to a connecting frame 1004, and the connecting frame 1004 is fixedly connected to the runner 902. A forward-rotating screening push paddle 1102 is fixedly installed on the right inner wall of the screening circle 1001, a reverse-rotating screening push plate is fixedly installed on the left inner wall of the screening circle 1001, and the left outer wall of the screening circle 1001 is fixedly connected to the forward-rotating stirring paddle 1102. By setting the forward-rotating screening pusher 1102 and the reverse-rotating screening pusher 1003, when the driving motor 2 901 rotates forward, the building materials are pushed toward the middle of the screening circle 1001, and the building materials are continuously screened. When the driving motor 2 901 rotates reversely, the reverse-rotating screening pusher 1003 pushes the materials from the screening chamber 502 to the left into the stirring chamber 501, and the forward-rotating screening pusher 1102 blocks the materials coming from the air separation cylinder 4 to prevent them from entering the screening chamber 502.

[0025] like Figure 16As shown, a counter-rotating propeller 1201 is fixedly connected to the inner wall of the feed cone 12 near the center, and a plurality of groups of feeding holes 1202 are fixedly provided on the outer wall of the feed cone 12 away from the center. A baffle 1202A is fixedly connected to the feeding hole 1202. By setting the baffle 1202A, the material entering the feeding hole 1202 is prevented from accidentally slipping during the rotation of the drum 6, which affects the efficiency of the feeding hole 1202 in conveying the material. When 02 is at the bottom of the drum 6, the soaked building materials on the drum 6 are pushed in to the right. As the drum 6 rotates, when the loading hole 1202 is at the top of the drum 6, the material contacts the inner wall of the loading hole 1202, slides down under the action of gravity, and falls into the spray drum 13, completing the transfer of the material; the right side wall of the feed cone 12 is fixedly connected to the counter-rotating stirring paddle 1101, and a plurality of water holes 1203 are fixedly opened on the feed cone 12.

[0026] like Figure 13 、 Figure 14 and Figure 15 As shown, multiple groups of forward-rotating water-washing propellers 601 are fixedly installed on the inner wall of the drum 6, and multiple groups of reverse-rotating water-washing propellers 1301 are fixedly connected on the inner wall of the spray drum 13. Figure 17 As shown, multiple groups of positive-rotating blades 701 are fixedly connected to the inner wall of the discharge valve tube 7, and a transmission pipe rack 702 extends outward from the left side of the discharge valve tube 7. A rotating groove 701A is fixedly opened in the center of the transmission pipe rack 702. The inner wall of the rotating groove 701A is rotatably connected to the spray pipe 14, and the spray pipe 14 extends inward into the spray drum 13.

[0027] like Figure 18 As shown, the power mechanism 8 includes a fixed frame 801, the top of the fixed frame 801 is rotatably connected to the transmission tube frame 702, a driving motor 802 is fixedly installed on the fixed frame 801, a small pulley is fixedly connected to the output shaft of the driving motor 802, the small pulley is connected to a belt 803, the other end of the belt 803 is connected to a large pulley 804, and the large pulley 804 is fixedly connected to the transmission tube frame 702.

[0028] Processing process: 1. Construction waste is first crushed by crusher 1, and then adsorbed by magnetic separator 3 on conveyor belt 2, which separates the metal objects such as steel bars. Then, it enters air separation drum 4 along conveyor belt 2 again; 2. After the construction waste is winnowed, light waste is separated and the construction materials enter the screening mechanism 10 for screening. Small particles of loose materials are discharged from the fine material outlet 502A. 3. Large particles of building materials fall into the mixing chamber 501 and are repeatedly pushed and soaked by the mixing mechanism 11, causing friction and collision between them, removing impurities such as dirt attached to the materials; 4. The building materials enter the drum 6 and are repeatedly soaked and sprayed under the joint action of the drum 6 and the spray drum 13. Finally, the cleaned materials are discharged from the slag discharge valve pipe.

[0029] Working principle: When the second drive motor 901 is controlled to rotate forward and the first drive motor 802 is controlled to rotate reverse: 1. After air separation, the building materials continuously enter the screening mechanism 10 through the opening 407 and are continuously screened in the screening circle 1001. At this time, the materials in the screening chamber 502 cannot flow leftward into the stirring chamber 501. 2. The materials in the stirring chamber 501 are pushed leftward toward the rotating drum 6 and the spraying drum 13 for repeated soaking and spraying operations. 3. The discharge valve pipe 7 prevents the materials in the rotating drum 6 from being discharged.

[0030] When the second drive motor 901 is controlled to rotate in the forward direction and the first drive motor 802 is controlled to rotate in the forward direction: 1. The material in the mixing chamber 501 is prevented from entering the drum 6 and can only be continuously mixed in the mixing chamber 501 to fully remove the dirt. 2. The material in the drum 6 and the spray drum 13 is uniformly pushed to the leftmost side of the drum 6 and discharged from the discharge valve pipe 7, completing the treatment of construction waste. When the second drive motor 901 is controlled to rotate in the reverse direction and the first drive motor 802 is controlled to rotate in the reverse direction: 1. The material in the air separation cylinder 4 is prevented from entering the screening mechanism 10; 2. The fully screened material originally in the screening mechanism 10 is pushed to the left into the stirring mechanism 11 for stirring; The present invention crushes the construction waste by a crusher 1, and then separates the metal such as steel bars in the construction waste by a magnetic separator 3 during transportation. Then, with the cooperation of an air separation mechanism 9 and an air separation drum 4, light waste such as plastic in the construction waste is separated, and the sorted materials are screened. By setting a spray drum 13, a drum 6 and a stirring mechanism 11, the screened construction materials are washed with water for multiple times. The materials are first repeatedly pushed and rubbed by the stirring mechanism 11 in the stirring chamber 501 to remove the mud on the outer layer of the materials that is difficult to clean. After the soil and other materials are stripped off, when the materials enter the drum 6, they can be repeatedly soaked and sprayed to ensure the water washing effect of the building materials; the water sprayed from the spray pipe 14 first sprays and cleans the materials in the spray drum 13, and the water flow that has been flushed once enters the drum 6 to soak the materials for the first time, and then enters the stirring chamber 501 through the water hole 1203 to soak the materials in the stirring friction for the second time, helping the soil to separate from the materials, and finally the cleaning wastewater mixed with soil is discharged from the drain outlet 501A, so as to make full use of water resources.
